Sperm biology and control of reproduction in sturgeon: (II) sperm morphology, acrosome reaction, motility and cryopreservation
Original language description
In the present review, sperm morphology, acrosome reaction, motility, short-term storage and cryopreservation are summarized and discussed in sturgeon (Chondrostei, Acipenseriformes). The elongated head of spermatozoon comprises an acrosome with 8-12 posterolateral projections. Usually three endonuclear canals are observed in the nucleus. Proximal and distal centrioles and 3-6 mitochondria are located in the midpiece region. The flagellum consists of an axoneme with a typical "9 + 2" structure of microtubules and presents a ribon-like structure due to two lateral membranous fins. Egg water, Ca2+ and Mg2+ can trigger acrosome reaction. Trypsin- and chymotrypsin-like activities are reported in sturgeon sperm. These physiological properties of sturgeon sperm are identified as serine activity with 33 kDa molecular mass and can be inhibited by their respective inhibitors. The K+ prevents sperm activation in seminal plasma, and hypo-osmolality or decrease of extracellular K+ triggers sperm a
